max requested capacity (%s) less than or equal to min (%s)

Error message

max requested capacity (%s) less than or equal to min (%s)

What it means

Fires in expandVolume: the requested maximum capacity is smaller than the requested minimum (both humanized in the message); a valid expansion needs max >= min, indicating the claim's capacity fields were swapped or mistyped.

Solutions

1. Set min_requests_max greater than or equal to min_requests_min in the claim
2. Re-issue the volume claim/expansion with corrected capacities
